Fruit Vendor [manda]

[mikemeister_admin]

Went back to see Mike's video solutions and cheated with his settings straight away, every thing seemed very straight forward until I tried to remove the green cast on the left side of the brushed steel frame.

I chose to try CYMK



Struggled for a while and resorted to using multiple neutral points, masking out the fruit in PS



My delight at finding one neutral point using manual curves (I'm easily pleased)



End result:



Things I've learnt:
to use the neutral points
to pay close attention to the hue clocks

Thinks I'd like to know:
Initially I was locking the curves and trying to remove the green cast manually.  I was also trying to use the 'remove blue from shadows' techniques.  I know 'colour casts' is a huge topic, what do you do?

Colour Worms - thanks to Greg for highlighting this topic - http://www.curvemeister.com/wiki/index.php?title=Color_Worms.  Am I right in thinking that worms close together are more likely to affect each others colour tones than those further apart when making curve adjustments?

Your second image really has the neutrals fixed well, using a mask, though, means the green cast is still in the fruit, though it is harder to see it is like a blue veil covering the image.

If the worms are close together on the RGB or CMYK composite curve, it means the color is close to gray, and that modifying the curve at that location is less likely to distort the color.  I am often lazy, and will resort to using the composite curve.  This is bad.  It's better, in general, to find the key colors you care about (neutrals, skin tones), and modify the individual curves to maintain those colors while getting the effect you want (increased contrast).

Manda,
If the colors are not overlapping then yes your statment is true. 
If you adjust the RGB curve you will effect the other colors by moving the curve. 
If you go to the G curve and adjust it you will not effect the R or B curves. 
The composite curve is the place that this is most effected.

Thanks to both of you for your answers.

You are right about the 'blue veil' - I kept my eye on the 'white' carrier bag to the right which has a lot of blue on it.

I'm going to play with 'blend if' controls tonight.  I'm wondering if I can control what colours to reveal in RGB whilst maintaining neutrals.

Come on Zog - I know you will have an idea about this.
